Effects of Stress and Other Factors on Opiate Drug Choice.

Completed

Conditions studied: Heroin Dependence, Opioid-Related Disorders

In brief

The purpose is to study the extent to which stress and other factors, including money, the amount of drug available and the amount of work effort, affect drug choice. This study will assess whether exposure to yohimbine, a drug stressor, increases opioid craving- and -seeking behavior. We will determine whether these behavioral outcomes are associated with biobehavioral stress markers: increased saliva cortisol levels, cardiovascular response (heart rate and blood pressure), and negative mood state.
